7.7.1. GHB and BTAC data corruption

The scheme provides parity error support for GHB RAMs and
BTAC RAMs but this support has limited diagnostic value. Corruption
in GHB data or BTAC data does not generate functional errors in
the Cortex-A9 processor. Corruption in GHB data or BTAC data results
in a branch misprediction, that is detected and corrected.
